Mine gets 11 mpg at 75 mph and 14 mpg at 65 mph. That tells you the whole story right there. It tells you that the biggest reason fuel economy sucks in these Jeeps is their aerodynamics. They fight...

I think of it the same way I think of most modern vehicles: excessively large, unnecessarily complicated, overpowered, and obnoxiously styled. Just gross excess all around.

A leaking exhaust valve stem seal won't foul the spark plug. It'll smoke out the exhaust, but that's because the oil is burning in the hot exhaust. It's not actually burning in the cylinder.

I have no problem with a converter so long as it's not restrictive, which a good cat isn't. I like how they quiet the exhaust down further, too.

My guess is there is no spec for them.

Typical torque for a 5/16 or 3/8 bolt is 15 to 25 foot-pounds.
